Abstract (en)
An apparatus (10) and a method for clamping a cope (8; 13) and a drag (7; 12) are disclosed. The apparatus prevents the cope from floating in molten metal when it poured in the mold space formed by the cope and drag and prevents their deformation due to the expansion of the molten metal when it solidifies. The apparatus includes a grid frame (4) extending in a horizontal plane for covering the top of the cope. The grid frame (4) has a plurality of openings (3, 3) and connecting members (5,5) mounted at opposing sides of it for engaging with engaging members (22; 11A) mounted at the drag side.
